APPARATUS FOR USE IN MAKING CONNECTIONS BETWEEN THE ENDS OF CABLES ANDTHE LIKE.

Original application filed July 9, 1923, Serial No. 650.262, and inGermany August 12, 1922. Divided and this application filed December. 5,1925. Serial No. 73,382.

This application is a division of application Serial Number 650,262,filed July 9, 1923, and entitled Method of making con nections in cablesand the like.

The present invention relates to apparatus for use in making connectionsbetween the ends of rods, tubes, wires, ropes and the like, andparticularlyto a tube-drawing device for such use.

For convenience of descr'i tion, the term bodies such as cables wil beemployed throughout the following description. and claims to designatethe rods, tubes, cables, wires or the like which maybe connected by thenovel apparatus.

In accordance with the invention described in my copending application,connections between the ends of bodies such as cables are made byinserting the ends of? the bodies in a tubular casing, which casing is;then subjected to a drawing or rolling operation to effect an intimateengagementbetween the casing and the bodies to be connected.

An object of the present invention is to provide a simple and eflicientdevice for use 1n connecting the ends of bodies such as cables. Anobject is to provide a device for effecting the contraction of a tubularsleeve into engagement with the end of a body such as a cable and theconcurrent flow of the material of the sleeve along the cable or thelike. A further object is to provide a device for drawing down a tubularcasing which is placed over the end of a body such as a cable. Morespecifically, an object is to provide a portable metal-drawing devicefor use in making connections between the ends of bodies such as cables.

These and other objects of the. invention will be apparent from thefollowin description when taken in connection wit the ac companyingdrawings, in which' Fig. 1 is a central longitudinal section showing oneembodiment of the invention with the cable ehds and sleeve positionedtherein.

Fig. 2 is a plan view of. the device, and

K Fig. 3 is a section on line 3+3 of Fig. 1,

- showing a draw carriage and associated elements. I I

In the drawings, the numeral 1 indicates the skeleton frame in which aremounted 'as an abutment to hold the sleeve bushings 2, 2 for rotatablysupporting a spindle having right-hand and left-hand threaded portions.3, 4, respectively. One

or both ends 5 of the spindle are made of square or other non-circularcross-section to receive an operating crank or wrench.

On the spindle 3, 4 are mounted carriages.

to receive the respective draw. Plates 11,12,

which plates likewise consist of two parts separable in a longitudinalplane. The top caps of the. socket members may be clampedto therespective basesections by bolts 13, 14.

As shown in Figs. 1 and 3, the adjacent ends of a stranded cable C arein position to be joined by drawing the tubular casing S' into which theends of the cable have-been inserted. The sleeve S is preferablyprovided with a reduced central portion having a diameter somewhat lessthan the diameter of the openings in the dieplates 11, 12. The sleeve Sis placed in the device by loosening the clamp bolts 13, 14 topermit'the separation of the two-part die plates and sockets. The boltsare then tightened and the ends of the cable are slippedinto the ends ofthe sleeve S. The spindle is then rotated by -means of a crankor wrenchapplied-to the .plates 11, 12- which are used have openings of such sizeand shape as to'produce the desired flow of the casing material intointimateengagement with the members to be joined. a I

- It will be noted that each draw late acts S against the pull of theother draw plate, and that it is not necessary to clamp the cables to-pre vent the se aration of their ends during the drawing 0 the sleeve.

While Ihave illustrated a device having oppositely movable draw platesfor simultaneously drawing both ends of the sleeve,

' it will be apparent that but one moving carriagemay be provided, ifdesired. 'The embodiment illustrated is particularly adapted for useinthe field as it is small and of relatively light weight. For shop orfactory use, the threaded spindle may be operated by power, if desired.It will be apparent that these and many other changes which may be madein the several parts, their relative size, shape and location fallwithin the scope of my invention as set forth in the following claims.

.2. Apparatus for drawing a tubular casing upon the abutting ends ofbodies such as cables, including two draw plates and means forsimultaneously operating the draw plates in relatively oppositedirections.

3. Apparatus for drawing a tubular casing upon the abutting ends ofbodies such as cables, including a'spindle provided with right and lefthand threads running in opposite directions from a common point, a framerevolubly supporting the spindle, car riages on the spindle travellingin opposite directions and a draw plate supported on each carriage.

A. Apparatus for drawing a. tubular casing upon the abutting ends ofbodies such as cables, including two draw plates, each composed of twolongitudinally divided parts, a holder for each draw plate composed oftwo longitudinally divided parts and means for simultaneously moving theholders in relatively opposite directions.

In testimony whereof, I aflix my signature.
